The Pirates received an incredibly encouraging start yesterday from young righty Jameson Taillon, who returned from the DL after being treated for testicular cancer. As Stephen Nesbitt of the Pittsburgh Post-Gazette writes, that outing coincidentally came against the Rockies, meaning that Chad Bettis — who has also battled the same affliction — was on hand. Of course, the road back has not been quite as straightforward thus far for Bettis, who needed chemotherapy, though he has now progressed to participating in long toss. The two right-handed hurlers have communicated often this year, Nesbitt writes in an interesting piece.

Here’s more on some health situations from around the game:

Orioles slugger Chris Davis left last night’s contest with what the team is calling a right oblique strain. He is undergoing an MRI this morning, as Jon Meoli of the Baltimore Sun tweets. Skipper Buck Showalter expressed a generally pessimistic view of Davis’s outlook after the game. Indeed, it’s likely that Davis will head to the DL, according to Jon Morosi of MLB.com (via Twitter), though there’s still nothing official. It’s tough news for a fading O’s team.

Also failing to make it through yesterday’s game was Mets star Yoenis Cespedes, who only just returned from a DL stint for leg muscle issues. It turns out, though, that he was dealing with pain in his left heel, as Laura Albanese of Newsday tweets. The heel is actually a long-term issue, rather than a new injury, and it seems there’s hope that it won’t limit Cespedes too significantly. That’ll surely be the team’s hope, as it attempts to climb back from a dreadful start to the season.

Astros outfielder Josh Reddick was diagnosed with a “mild concussion” after running into the outfield wall, as Mark Berman of FOX 26 was among those to tweet. His outlook isn’t yet known, and surely depends upon further medical evaluation today. Reddick has provided Houston with a quality .281/.338/.443 batting line though 238 plate appearances, helping the organization to the best record in baseball and a dozen-game lead in the AL West.

The Pirates have optioned starter Tyler Glasnow and reliever Dovydas Neverauskas to Triple-A Indianapolis, MLB.com’s Adam Berry tweets. The idea, as Stephen J. Nesbitt of the Pittsburgh Post-Gazette tweets, is that Jameson Taillon will return and start on Monday, with Chad Kuhl pitching in Glasnow’s rotation spot on Wednesday. There’s no official word on who will Glasnow and Neverauskas on the roster in the short term, although the agent for righty reliever Edgar Santana recently tweeted congratulations to his client for making it to the big leagues for the first time.

Of these moves, the most newsworthy is Taillon’s quick return. Taillon had surgery for testicular cancer in early May and returned almost immediately, hopping back into baseball activities and then making three rehab starts in the high minors during which he showed little rust. That he will have been able to rejoin the Pirates’ rotation so quickly is heartwarming news after his shocking cancer diagnosis. Before his surgery, he had a 3.31 ERA, 7.6 K/9 and 3.3 BB/9 over 31 1/3 innings this season.

Glasnow, who once joined Taillon atop lists of the Pirates’ best pitching prospects, has struggled greatly this season, posting a 7.45 ERA, 8.3 K/9 and 4.8 BB/9 over 54 1/3 innings. The 23-year-old has size and elite stuff, with a mid-90s fastball and an excellent curveball, but he has made little evident progress in the development of his control.

In welcome news, the Pirates have announced that right-hander Jameson Taillon will begin a rehab assignment at Double-A on Sunday, which should put him in position to return to the majors by late June. The 25-year-old Taillon underwent surgery for testicular cancer on May 8 and was cleared to resume baseball activities less than two weeks later.

More from the National League:

Mets ownership has given no indication that manager Terry Collins is in danger of losing his job, but the skipper does have critics within the front office, reports Marc Carig of Newsday. After back-to-back playoff seasons – including a World Series berth in 2015 – injury-plagued New York has gotten off to a 20-26 start this year and Collins’ bullpen management “has left some Mets officials fuming” along the way, writes Carig. However, Collins has the full support of owner Fred Wilpon, according to Carig, and could survive the season. The 68-year-old Collins became the longest-tenured manager in Mets history last week, having taken the reins back in 2011. He’s in the final year of his contract.

The Cubs have relegated left fielder Kyle Schwarber to a platoon role for the time being, meaning the lefty-swinger won’t face southpaws, manager Joe Maddon told reporters Friday (via Mark Gonzales of the Chicago Tribune). “If he’s not swinging the bat well against righties, it’s a bad assumption he’s going to do well against lefties,” said Maddon, who sat Schwarber against Dodgers lefty Alex Wood on Friday. “I’m just putting him in a deeper hole by throwing him out there just based on really bad logic.” The powerful Schwarber, 24, entered the season with no shortage of hype after missing nearly all of last year with torn knee ligaments, but he has stumbled to a .183/.303/.356 line in 188 plate appearances (.147/.310/.265 in 42 tries versus lefties).

Brewers first baseman Eric Thames has already been tested for performance-enhancing drugs at least five times this year, but the league isn’t conspiring against the slugger, writes FOX Sports’ Ken Rosenthal. Rather, drug testing has gone up across the majors thanks to the new collective bargaining agreement, which likely explains Thames’ regular tests, posits Rosenthal. Thames was also tested “frequently” as a superstar with the Korea Baseball Organization from 2014-16, but there’s no account of a failed test there or with the Brewers, sources told Rosenthal.

MAY 18: Taillon’s pathology report did indeed come back positive for testicular cancer, reports MLB.com’s Adam Berry. While there’s no timetable for his return to the mound, Taillon has been cleared to resume light baseball activities, according to Berry, which is certainly good news. Taillon has been at PNC Park with his teammates this week and has played catch in addition to participating in some light cardiovascular work. Taillon is slated to be re-examined next week.

MAY 8: Pirates righty Jameson Taillon has undergone surgery for what is suspected to be testicular cancer, according to a team announcement. MLBTR sends Taillon its very best wishes for a full and speedy recovery.

At present, the ensuing treatment plan has yet to be decided. “Further testing” will be required before a course is charted, according to the team, with updates to be announced “as appropriate.”

Needless to say, Taillon’s overall health and well-being are much more important than his playing status, but it seems reasonable to anticipate that he’ll be sidelined for at least some time. Pittsburgh had already called up Josh Lindblom to take the roster spot of Taillon, who has been placed on the 10-day DL.

The news immediately calls to mind the situation of Rockies righty Chad Bettis, another promising young starting pitcher who has battled testicular cancer. In his case, the hope was that an offseason procedure would clear the way for a full return to health both on and off the mound. Unfortunately, Bettis ultimately required chemotherapy when it was discovered that the cancer has spread. He is expected to miss most or all of the current season.

The hope remains both that Bettis will get back to full health and that Taillon’s own course will be more straightforward. In the meantime, it’s a good reminder for everyone to monitor for these and other ailments. As Bettis said upon his initial diagnosis: “This only reinforces my belief that each of us needs to be totally in tune with our own physical health, and that taking action sooner than later when we feel like something is off can sometimes literally be the difference between life and death.”

Taillon’s own statement is also well worth a full read (via his Twitter account). This challenge, like others he has faced, has “just added fuel to my burning fire,” he writes, continuing: “Today I lost a piece of my ’manhood.’ But, today I’m feeling like more o a man than I ever have.”

The Pirates have placed right-hander Jameson Taillon on the disabled list, retroactive to Thursday, with groin discomfort, per a team announcement. To take Taillon’s roster spot, the Pirates have selected righty Josh Lindblom’s contract from Triple-A Indianapolis.

Fortunately, the 25-year-old Taillon’s injury is not related to the hernia surgery he underwent in 2015, according to the Pirates, but his absence will nonetheless be a blow to the scuffling club’s rotation. Although Taillon’s walks per nine have risen from 1.47 per nine innings as a rookie last season to 3.31 this year, the hard thrower still ranks first among Pirates starters in ground-ball percentage (52.9), second in ERA (3.31) and third in innings (35 1/3). Taillon, Gerrit Cole and Ivan Nova have formed 60 percent of a formidable rotation, but the team’s other two starters, Chad Kuhl and Tyler Glasnow, have struggled.

For now, Taillon’s rotation spot will go to Trevor Williams, who debuted in the majors last season and has come out of the bullpen in 12 of 13 appearances. In six relief outings and 11 2/3 frames this year, Williams has logged a 5.40 ERA, 7.71 K/9, 5.4 BB/9 and a 27.8 percent grounder rate.

The 29-year-old Lindblom, meanwhile, is now in position to make his Bucs debut after signing a minor league deal with the organization over the winter. The former Dodger, Phillie, Ranger and Athletic has served almost exclusively as a reliever, having made just six starts in 110 appearances, and has recorded a 3.82 ERA, 7.97 K/9, 3.82 BB/9 and a 33.3 percent grounder mark over 136 2/3 innings. Lindblom hasn’t pitched in the majors since 2014, when he tossed 4 2/3 frames with Oakland.

The Pirates designated catcher Erik Kratz for assignment, per a team announcement. Pittsburgh has activated fellow receiver Francisco Cervelli, precipitating the move. The Bucs also announced that Jameson Taillon has been activated, with fellow righty Chad Kuhl optioned to make way.

The 36-year-old Kratz has endured an awful year offensively, recording only eight hits in 87 plate appearances, and owns a lifetime .200/.248/.362 batting line at the major league level. Like many veteran receivers, though, he’s valued more for his work behind the dish. It seems likely that he’ll either stick with the Pittsburgh organization after clearing waivers or move on to provide depth to another club.

The Pirates have prized rookie right-hander Jameson Taillon on the 15-day DL due to fatigue in his throwing shoulder. Southpaw Steven Brault will start tomorrow’s game against the Cardinals in Taillon’s place, and another move will need to be made to create space for Brault on the 40-man roster.

Taillon missed all of the 2014 and 2015 seasons recovering from both Tommy John surgery and a hernia operation, and he returned to dominate over 61 2/3 IP at Triple-A. That dominance (as well as some injuries to the Pirates’ rotation) led to two separate callups this season, and Taillon acquitted himself pretty well in his first taste of big league action. The 24-year-old righty had a 3.86 ERA, 6.8 K/9 and 4.20 K/BB rate over 28 innings with the Pirates, and he looked in good form during his last start on June 29, holding Seattle to one run on six hits over six innings.

The Pirates were naturally going to be careful with Taillon’s innings given his long injury layoff and the fact that he’d never thrown more than 147 1/3 frames in any one pro season. This could very well be a precautionary DL stint based on Taillon showing the first hint of an issue, though obviously any type of shoulder-related DL stint is troubling given Taillon’s importance to Pittsburgh’s rotation plans in both the long and short term.

The Bucs’ pitching staff has been plagued by injuries (Taillon joins Gerrit Cole and Ryan Vogelsong on the DL) and underperformance from Francisco Liriano, Jeff Locke and Jon Niese. Chad Kuhl has already gotten the call from Triple-A to bolster the rotation, and one has to wonder if the Pirates will promote another top prospect by bringing Tyler Glasnow to the bigs. Glasnow has a 1.78 ERA and 10.6 K/9 over 96 Triple-A innings this season, though he has also posted a troubling 4.9 BB/9.

Brault was rated as the 15th-best minor leaguer in Pittsburgh’s system by the 2016 Baseball America Prospect Handbook. He was credited with having excellent command and an ability to limit homers and induce grounders, which helps counter an “ordinary” changeup and curve, and a fastball in the 89-91 mph range. Brault has a 3.34 ERA, 11.3 K/9 and 2.93 K/BB rate over 35 Triple-A innings this season.

The Pirates announced that they have placed ace Gerrit Cole on the 15-day disabled list due to a right triceps muscle sprain, as MLB.com’s Adam Berry tweets. Right-hander Jameson Taillon has been recalled from Triple-A Indianapolis to make tonight’s start — the second big league outing of his career. Cole’s DL stint is retroactive to June 11.

Cole, 25, has worked to a 2.77 ERA this season that closely matches last season’s 2.60 mark, although his strikeout (7.2 K/9), walk (2.6 BB/9) and ground-ball (42.9 percent) rates have all trended in the wrong direction this year. He exited his most recent start after two innings due to tightness in his triceps, and the Pirates had been hopeful that he’d only miss one start, but it appears he’ll be sidelined a bit longer than that at this stage. Whether his DL stint extends beyond the minimum 15 days remains to be seen.

The 24-year-old Taillon has made a dominant return to the mound in 2016 after missing the 2014-15 seasons due to injury. In 61 2/3 innings at the Triple-A level this season, Taillon has a 2.04 ERA with a brilliant 61-to-6 K/BB ratio, and he turned in a quality start in his first big league effort last week when he held the Mets to three runs on six hits and two walks with three strikeouts across six innings. He’ll tangle with the Mets once again tonight — this time on the road in New York. Taillon doesn’t appear to quite be in the Bucs’ long-term rotation plans for this season just yet, as he was optioned following his recent appearance. Cole’s health could play a role in those plans, of course, though one would also imagine that Pittsburgh will be mindful of Taillon’s innings count following a two-year layoff from taking the mound in a game setting.

Jameson Taillon’s much-anticipated Major League debut will come tomorrow, as the Pirates announced earlier today, but GM Neal Huntington implied that the young right-hander’s promotion may be rather short-lived in nature. Via Rob Biertempfel of the Pittsburgh Tribune-Review (Twitter link), Huntington said: “This may be a spot start for Jameson. A lot of that decision will be beyond his control.” Taillon has utterly dominated Triple-A Indianapolis this season, posting a 2.04 ERA with a 61-to-6 K/BB ratio in 61 2/3 innings, spanning 10 starts. One has to imagine that innings are a concern for the Pirates when it comes to Taillon, as injuries prevented the former No. 2 overall pick from pitching in both 2014 and 2015.

Here’s the latest from the National League:

Right-hander Justin Masterson will take Taillon’s spot on the roster at Indianapolis, tweets the team’s media communications coordinator, Ryan Sheets. Masterson sat down recently with Charlie Wilmoth of MLBTR and SB Nation’s Bucs Dugout to discuss his rehab from shoulder surgery, his decision to sign with the Pirates and the long-term talks he had with Cleveland prior to hitting the open market in the 2014-15 offseason. Masterson acknowledged that his shoulder hasn’t been in great shape for quite some time and implied that it could’ve derailed an agreement in Cleveland even if one had been reached. He also praised the Pirates organization as an appealing landing spot and added that the location of the club’s Triple-A affiliate, in Indianapolis where he makes his home, was alluring as well.

Service time considerations played an oft-noted role in the promotional timeline of young Cubs star Kris Bryant, leading to a still-pending grievance. As Gordon Wittenmyer of the Chicago Sun-Times reports, though, Bryant calls the matter a thing of the past. While the actual grievance proceeding has yet to reach a hearing, with all involved seemingly waiting for the new CBA to be negotiated, Bryant says it “never even crossed [his] mind” entering the season. “For me it’s just important to continue to go out there and do what I do, so that I can help the team in any way possible in where we’re at today,” Bryant said. “It’s just important for me to not even worry about it right now because it takes away from so much of what we have going this year. And that was last year’s news.”

Phillies manager Pete Mackanin says that he’s nearing a resolution of the team’s first-base situation, as Corey Seidman of CSNPhilly.com reports. It seems quite possible that Tommy Joseph will receive the official designation as the starting first bagger, which is essentially the way things have been trending anyway. That would put Ryan Howard in a tenuous position, though it’s not at all clear whether Philadelphia has any intentions of cutting him loose. The 24-year-old Joseph is off to a nice .311/.313/.590 start over his first 64 MLB plate appearances, while the 36-year-old Howard is mired in a .150/.210/.333 opening to the year. In years past, we’ve talked about the former star slugger as a possible trade chip who might allow the Phillies to save some cash. Now, however, it seems he’ll either finish out the season in a limited role or end up hunting for another team on the open market.

Dodgers right-hander Brandon McCarthy will begin a minor league rehab assignment within a week, manager Dave Roberts told reporters, including Andy McCullough of the Los Angeles Times (Twitter link). McCarthy had Tommy John surgery just weeks into the first season of a four-year, $48MM contract with the Dodgers and has been rehabbing since undergoing the operation late last April. A return to health would be a nice boost to a Dodgers rotation that has been ravaged by injuries, though he’ll of course need some time to build up innings in the minors. As for another of the Dodgers’ injured starters, Hyun-jin Ryu, Roberts said the team still doesn’t know when the left-hander will appear in a game at any level. Shoulder problems have sidelined Ryu for much of the past two years.

The Pirates will promote highly-regarded pitching prospect Jameson Taillon for his major league debut tomorrow, per a team announcement. He’ll square off against the defending NL-champion Mets in his first taste of the bigs.

Taillon, the second overall pick of the 2010 draft, moved steadily up the ranks in the Bucs’ farm before he was derailed by injuries. First came a lengthy absence for Tommy John surgery, then a hernia. The hope had been that he’d be available this time last year, but the Pirates may yet be rewarded for their patience.

Though he last appeared professionally in 2013, the 24-year-old righty has returned with a vengeance in 2016. Over 61 2/3 innings at the Triple-A level, Taillon carries a 2.04 ERA. He has allowed just 44 base hits and is walking less than a batter per nine while recording a sturdy 8.9 K/9 strikeout rate.

Of course, the move also comes at a point where Taillon is unlikely to qualify for Super Two status. Even if he’s able to stick in the majors the rest of the way the top prospect could only accumulate 118 days of service.

As Taillon tells Wilmoth, the Super Two matter isn’t one that concerns him. “As far as the Super Two rule goes,” he said, “I’d hate for that to be a reason to keep someone down if they’re 100 percent ready, but I felt like I actually had something to work on, so that kind of cancels it out for me.”

It remains to be seen not only whether Taillon can perform, but also what kind of role he might play the rest of the way. His long layoff raises the specter of an innings limit; while he has worked to over 140 frames in two prior seasons, he missed two full campaigns in the interim.

Manager Clint Hurdle did note that the long layoff gives Taillon “a full gas tank” to work with, though he also suggested that a permanent rotation spot is no sure thing. Per the skipper, factors both in and out of Taillon’s control will determine the team’s course moving forward. (Reporting via Rob Biertempfel & Travis Sawchik of the Pittsburgh Tribune-Review, Twitterlinks, and Stephen Nesbitt of the Pittsburgh Post-Gazette, via Twitter.)

Even if Taillon doesn’t hold down a starting job for all of 2016, he — and similarly hyped youngster Tyler Glasnow — could have a major impact on the Pirates’ fate this year. As I explained in listing those two among twenty prospects whose promotions could alter the trade deadline, both could have an impact as starters and/or relievers, deepening the staff and shifting the club’s role in the market this summer.
